Recording medium management method

Abstract

In the case of recording computer data, e.g., into clusters 16 to 27 of the data recording area, the range of clusters 16 to 27 is ensured as an available range in a management table (parts table) of U-TOC. For example, onto parts table of No. 02h, such computer data is recorded as a segment in which cluster 16 is caused to be start address and cluster 27 is caused to be end address. For the purpose of carrying out management of recording state of computer data, FAT (File Allocation Table) is separately provided. At this table, management of recording states of clusters 16 to 27 is carried out. Thus, computer data can be recorded onto mini-disc for recording audio data.

We claim: 
     
       1. A data recording method of recording digital data onto a recording medium, the method comprising the steps of: reading out, on the basis of data of a first table, a second table from tracks for digital data of the recording medium;   detecting information indicating available block from the second table;   recording digital data in blocks of the tracks for digital data corresponding to the information indicating available block; and   rewriting the information indicating available block of the second table into information indicating disabled block,   wherein in the case where the information indicating available block is not included in the second table,   the method comprises the steps of: detecting an empty area of the recording medium from data of the first table;   recording, into the first table, data indicating that the empty area is caused to be tracks for digital data; and   recording information indicating available block into the area for data of the second table corresponding to the block of the empty area caused to be the tracks for digital data.
